PROCESS AND EQUIPMENT FOR PEST DISPOSAL IN HERMETIC ENVIRONMENTS FROM THE APPLICATION OF PHOSPHINE (PH3) EXTERNALLY GENERATED AND RECIRCULATED

摘要

process and equipment for pest elimination in airtight environments from the application of phosphine (ph3) generated externally to the environment and recirculated. control of the purging process of stored grain; concentrated and controlled generation of phosphine gas (ph3) in hydrolysis reaction chamber, recirculation and monitoring of phosphine gas (ph3) concentration levels in the fumigated environment; The present patent describes a new modular process and equipment developed to accelerate and optimize the phosphide hydrolysis reaction in its various substrate versions (plates, tablets, pellets, sachets and strips), generating phosphorus hydride, enabling its recirculation and The main object of the present invention is to obtain fast and effective fumigation in airtight environments while still allowing gas recirculation. only needs one operator; leaves no process residues near the fumigated mass, can be fixed or on a wheel drive device, allows the process and supervision of the process locally or remotely, keeping the operator and other involved safe and outside the airtight place to be fumigated . It is cpu controlled with associated monitor and has built-in gprs data transmission system.
